Earth-Pressure--and-Retaining--Walls

A retaining wall 4m high has a smooth vertical back. The backfill has a horizontal surface in level with top of wall. There is a uniformly distributed surcharge load of intensity 36 KN/`m^3` over backfill. The unit weight of backfill is 18 KN/`m^3` and angle of shearing resistance is `30^0` and cohesion is zero. Determine magnitude and point of application of active pressure per metre length of wall.

This Chapter Earth-Pressure--and-Retaining--Walls consists of the following topics

Compute the intensities of active and passive earth pressure at a depth of 8 m in dry cohesionless sand with an angle of friction of `30^0` and unit weight of 18 KN/`m^3`. What will be the intensities of active and passive earth pressure if the water level rises to the ground level? Take saturated unit weight of sand as 22 KN/`m^3`.

There is a uniformly distributed surcharge load of intensity 36 KN/`m^3` over backfill. The unit weight of backfill is 18 KN/`m^3` and angle of shearing resistance is `30^0` and cohesion is zero. Determine magnitude and point of application of active pressure per metre length of wall.

In above problem, if water table rises behind the wall to an elevation of 1.5 m below the top, determine the total active pressure and ots point of application. Take submerged weight of sand as 12 KN/`m^3`. Assume that there is no change in angle of shearing resistance due to submergence.
